Subject Re: Adding new node to cluster
Date Tue, 17 Feb 2015 15:20:28 GMT
I know that UN is good, but what troubles me is the addition of the own node's ip in it's
yaml seeds section.

  Hi Bogdan
 In nodetool status:
   - UJ: means your node is Up and Joining
   - UN: means your node is Up and in Normal state
 UN in nodetool is good ;-)

  Hello all, 
  I have an existing cluster. When adding a new node, I saw that Opscenter saw the node in
an unknown cluster. In the yaml, the cluster name is the same. So i have stopped the node
and added it's ip address in the list of seeds. Now Opscenter sees my node. But nodetool status
now sees it as UN, instead of UJ when it first started. One other mension is that even if
I stop the node, remove it's ip from the list of seeds, Opscenter sees the node in the known
clustre but nodetool sees it as UN. I am not sure what the implications of adding a node's
ip in it's seed list are and I think that for the existing nodes I have might done the same.
Eg. started with it's ip in the seed list but after removing it and having to restart the
nodes for whatever reason, I did not see any changes. 
  Is my cluster ok, or what do I need to do to bring the cluster to a good state? 
  Thank you.
